TestMulitipleNNDataBlockScanner#testBlockScannerAfterRestart is racy
--------------------------------------------------------------------

                 Key: HDFS-3037
                 URL: https://issues.apache.org/jira/browse/HDFS-3037
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: test
    Affects Versions: 0.24.0
            Reporter: Aaron T. Myers
            Assignee: Aaron T. Myers
            Priority: Minor


In this test, we restart a DN in a running cluster, call MiniDFS#waitActive, and then assert
some things about the DN. Trouble is, MiniDFSCluster#waitActive won't wait any time at all,
since the DN had previously registered with the NN and the NN never had time to realize the
DN was dead.
